Solve the problem of Win7 local connection often dropped

Since the use of a wired router to access the Internet, I thought it was a router failure that caused the local connection to be disconnected. Later I tested the old notebook, everything is normal, also There is no drop of the line. However, after connecting the new laptop to the Internet, the local connection started to work normally. After half an hour, I found that I couldn’t get on the network. The X at the local connection indicates that the network is not available, but inserting the network cable into the old laptop is no problem, so the problem is basically judged in the new notebook. On, the author first entered the new notebook device manager, first disabled the network card, and then restarted the resulting network is normal, so you can conclude either the notebook network card problem, or set the problem, because it is a new notebook, the network card failure is very small, Therefore, the author thinks that the focus should be on the network settings, the solution is as follows:

1, first click on the Win7 desktop "network", enter the network settings, and then click on the top of the "Network and Sharing Center" Figure:
Enter Win7 Network and Sharing Center

2. After entering the network and sharing center, we click on the left side of the "Change Adapter Settings", as shown below:

After this setting, the author's laptop no longer has an Internet connection that is often dropped or not recognized by the local network. In fact, the biggest factor here may be the default selection of IPV6, online access to information, many computer experts also feedback to remove the checkmark in front of IPV6, because the network we currently use is generally IPV4, check the IPV6 is easy to conflict Can be removed.
